RichTextBox Control And Socket Class
Nov 20, 2009
I am using a RichTextBox control and a Socket Class. When I use the AppendText function in Form_load it get's added, but not in the event when text is received.
Code:
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
client.Connect(URL, PORT)
RichTextBox1.AppendText("Connecting...")
End Sub
Private Sub client_onConnect() Handles client.onConnect
[Code] .....
Just so you know, the MessageBox showing in Data is working perfectly.

I wrote a server for a tcp/ip chat program using the system.net.sockets class. When I run the program and the client tries to connect to it, there's an error and it won't work. I am positive that the issue isn't with the client, as I have made a connection with the client before.
Imports System.Net
Imports System.Net.Sockets
Imports System.IO
Public Class Form1
Dim server As New TcpListener(IPAddress.Any, 60)
Dim client As New TcpClient

I am in the process of prototyping a small sockets application, which monitors IT infrastructure (due to in-house financial and deployment restrictions, I am unable to utilise an existing commercial or open-source solution). Basically, I have a server application and associated agent process for communicating heart-beat data to the server. The server application implements a TCP socket class (TCPDevice), which is called from a WinForm. I am aware of the restriction on updating the UI from processes running on separate threads, and that the preferred technique for acheiving this is via the use of Delegates in conjunction with the Invoke method. Having had very little need previously for using Delegates (apart from of course std windows events and the BackGroundWorker control), I am at a loss as to how to do this in the context of my application, and would appreciate some assistance, although it has occurred to me that I could use the backgroundworker for marshalling updates to the UI.
Eventually the application will need to update a grid of devices via feeds from the defined agents, however for the purpose of this exercise simply updating a status bar on the UI will suffice. The section of the code which I believe is relevant to propogating the code to the form is contained in the OnDataReceived method.Below is a code excerpt from the protoype app which should put the above into appropriate context:
Code from the form:

I'm writing a GUI-based app in VB.net that talks to a LambdaMOO server via telnet, sends commands to display the object hierarchy, then parses the output and creates a visual representation of the object hierarchy.So my question is: is there some kind of "telnet client" class for .NET to simplify the sending and receiving of data, or do I have to write my own using the socket API?

I am trying to create a socket class in my project to send data to ecr (electronic cash register).Ecr comes with software that listens for commands on port 3535. Command are in forms of XML Files. It has only one catch, I must close the connection on socket, so the ecr would know when to process the command and respond. Since I only send one command at a time,I need the simplest solution I can get.
How it works:I create the socket and connect it to 192.168.1.67:3535 I start
client.BeginReceive
Then I send the command with
client.BeginSend
And I do a
client.Disconnect(True)
so I can get response from ECR.And in 8 of 10 times it works just fine. The problem is this few times it doesn't work.At that time I cant receive anything because it reports that the client is not connected in ReceiveCallback but it still manages to send the data to ECR just fine. The bill comes out on the ECR, but I get no answer about what happened.
I call the class like this:
Dim dre As New HCPSocket
Result2 = dre.Otkucaj(Command1, "192.168.1.67")
Debug.Print(Result2)
dre = Nothing
End the class looks like this:
Imports System
Imports System.Net
Imports System.Net.Sockets

I'm trying to update an application from vb6 to vb.net. The orig app used the winsock control. Unfortunately I can't nor do I want to use it in the re-write. Are there any decent public classes with events that wrap the Socket class?

I wrote a Socket Client which will send the Socket Server some data and get some response from Server. This process will be running once in every 2 seconds.
Now what I need to know is How we can identify the connection lost between Server and Client?
I need this to be implemented in the Client side. If there is no connection then Client should automatically close the connection. Once the connection with the server is available in the next attempt it should connect automatically.

Example:
Two files - TestClass.vb, myForm.vb
TestClass.vb looks as follows:
Imports System.Threading
Public Class TestClass
Private myClassThread As New Thread(AddressOf StartMyClassThread)
[code]....
The result:Application runs, no errors or exceptions.Displayed is the listbox and the Start button.I press the start button and a msgbox says "Not Invoked" as expected and upon clicking OK to that msgbox "Start Button Pressed" is added to the Output listbox control.Immediately following that the msgbox pops up again and says "Not Invoked". I was expecting "Invoked" as a separate thread is trying to use the Output listbox control.Of course this results in the Output.Items.Add being attempted which results in no visible result as the thread is not allowed to directly update the UI control.

in the richtextbox(from my class) gotfocus -what I need is the richtextbox.text to also be in a different textbox on the form. the richtextbox(readonly) is from my class that has mousedown and mouseup code and more than one richtextbox (small in size) will be on the form in a container so when user clicks on one I need the richtextbox.text to also be in a regular textbox (not from my class) and not located in container. And I need to read a property I made in my richtextbox class.

I tried it and get an error but maybe I'm tring the wrong way. Can a usercontrol inherate an application defined class ie.. could you inheritance a classic rect class into a user control to add the hight and width properties to the control without having to do all the coding all over again? Currently I just declair a private instance of the class within the control and then encapsalate. It would be nice if I could just inherit all the functionality of my classes into controls designed to implament the classes.

Drawing on top of a RichTextBox control has always been a pain due to the Paint event, and related OnPaint() method being suppressed. Here is a bit of code that gets around this issue.The following derived RichTextBox will use a seperate NativeWindow control to hook into the message stream of the RichTextBox, listen for the WM_PAINT message, and then raise the Paint event on the RichTextBox for you.In this way, it is possible to use the Paint event handler of the RichTextBox control to paint on top of the control after it has performed its default rendering of the text.The following code is an initial implementation but appears to be pretty solid so far. 'Based in part on code located at: [URL]
''' <summary>
''' A RichTextBox object which raises, and utilizes, its own Paint event.
''' </summary>
''' <remarks></remarks>
[Code].....
I may continue to expand upon this idea, but I wanted to get the initial code out here as this seems to be the minimum to get the painting functionality to work.Reed Kimble - "When you do things right, people won't be sure you've done anything at all"

After scouring the inter-webs for info on printing in vb.net, it seems to me that it's pretty difficult.
My question is, is there a simple way to print something that is in a RichTextBox control?

I am working in vb2008. I understand how to set a richtextbox's selectedstart property to a text block using .find. I would like to know how to tell the richtextbox to scroll to the selected position based upon the find operation and show its position at the top of the window. I would like to pass text blocks into my richtextbox control and have the control automatically scrolll to that position if the text block is found.

I was checking out the internet to get some information on VScrollBar control in VB.NET, however I can't find any useful information on what I am trying to do, as I have never worked with VScrollBar before.
What I am trying to do is use a VScrollBar control to handle scrolling of two Richtextboxes (i.e. synchronized scrolling) because each line of richtextbox1 is associated with the corresponding line of richtextbox2.

I have read and played with code that streams output to a richtextbox but that is runningit from cmd.exe but I run kix32 programs like anything.kix using commmand line kix32 c:anything.kix and it can be run from a *.cmd file as well.
why havent' experts made a toolbox item/control that is say called console? like they seem to have many others dialogbox - browse box etc...? It has been years since VB.net has been out. why why dont they make one??huh? I have looked all over net and it ant no easy job either.
I mean all the code i see makes it very difficult you have to be an expert just to make the coding. Is there some class or something that maybe a beginner/intermediate might be able to tackle..
I just want the command line that is initiated by the kix32 engine to be streamed to my richtextbox in my gui vb.net program

I have just turned to using VB.net and would like to know why when I load an RTF (with tables in a 9x9 cell format) all appears in a 1x9 format...i.e. instead of loading the tables (some are side by side), they load up in series (below each other).
My simple line of code on a button is:
